Yes. New York education law 3204 requires all non-public schools to provide an education that is "substantially equivalent" to that of public schools. The list of required subjects can be found on the Department of Education’s website. It includes English, math, reading, writing, music, art, geography, U.S. and N.Y.S. history, science, physical education, and more. While public schools are more heavily regulated than private schools, the guidelines listed above do apply to private schools, and religious schools have the same legal and moral obligations as other private schools.
